What reviewers say
Reviewers praise its responsive gaming, deep blacks and vivid HDR picture, but find text clarity less convincing for desktop work. TechSpot found it quieter and more responsive than the original AW3423DW, while criticising HDR accuracy on the early firmware it tested. Both note the remaining risk of OLED burn-in with static content.
